Hi ChappaquaWriter,
Can you please provide few additional info so that we can understand the issue better?
1) Are you seeing this issue on a Win or MAC machine?
2) Have you tried relaunching captivate and inserting an Interaction?
3) are you able to see interactions in the 'eLearning Assets' location.
Win location :- C:\Users\Public\Documents\Adobe\eLearning Assets\Interactions
MAC location : - /Documents/My Adobe Captivate Projects/Interactions
4) If the interactions are present in the above location, then can you please try inserting the interaction through the 'Insert>Widget> select an interaction from the above location' and see its working or not?
Thanks,
Nimmy Sukumaran.
